Ownership without maintenance is delayed deterioration.

Nothing holds still. Left alone, everything you own is quietly moving toward its own failure, and maintenance is simply the act of slowing that down. Skipping it does not preserve the status quo; it just moves the deterioration somewhere you are not looking yet.

Rather than a full schedule, choose the three things whose failure would genuinely disrupt you and give each one its basic attention. Small and consistent beats thorough and abandoned. The point is not perfection, only keeping ahead of the drift.
